Description

Technical Field

[0001] The invention relates to a slide guide device for a press machine, in particular to a new type of automatic self-aligning and anti-eccentric load sliding guide device. Background Art

[0002] A press (including punching machines and hydraulic presses) is a general-purpose press with a sophisticated structure. It has the characteristics of wide application and high production efficiency. The press can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. It processes metal blanks into parts by applying strong pressure to the metal to cause plastic deformation and fracture. At present, the multi-station press production line completes multiple processes in one work stroke, such as blanking, stretching, punching, trimming, shaping, flanging, cutting, etc. It is a high-efficiency, highly integrated and automated press production line. However, since the first process involves more stretching processing, its load is greater than that of other processes, so it is easy for the multi-station press to produce eccentric loads.

[0003] Since the traditional guide rail is a traditional fixed plane, when the slider is subjected to an offset load, the slider guide rail has a slight rotational deviation, the guide rail will form a line contact, the contact pressure will increase greatly, and the guide rail contact surface will be damaged. Under this state, long-term production will seriously affect the slider operation accuracy, and will also affect the service life of the press transmission system and the mold. Summary of the invention

[0004] The purpose of the present invention is to provide a new type of sliding guide device with automatic self-aligning and anti-eccentric load, so as to solve the problems in the prior art.

[0005] The technical solution of the present invention is: a new type of automatic self-aligning and anti-eccentric load sliding guide device, the guide device comprises a ball seat, a joint guide rail, a slider guide rail and a slider; The ball seat is fixedly arranged on the press body, the joint guide rail is arranged in the ball seat, the slider guide rail is installed on the slider, and the slider guide rail is slidably connected with the joint guide rail.

[0006] Preferably, the outer surface of the joint guide rail is a spherical surface, the ball seat is provided with a spherical mounting groove, the joint guide rail is arranged in the spherical mounting groove, and the joint guide rail can rotate in the spherical mounting groove.

[0007] Preferably, the surface of the joint guide rail is provided with a guide surface 1 and a guide surface 2 which are perpendicular to each other, the outer surface of the slider guide rail is always in surface contact with the guide surface 1 and the guide surface 2, and the slider guide rail moves up and down along the two guide surfaces of the joint guide rail.

[0008] Preferably, the guide surface 1 and the guide surface 2 are smooth planes.

[0009] Preferably, an arc groove is provided between the guide surface 1 and the guide surface 2 on the joint guide rail.

[0010] The beneficial effects of the present invention are as follows: the ball seat and the joint guide rail are in spherical contact. When the slider is subjected to an offset load, the joint guide rail will rotate accordingly, but the joint guide rail and the slider guide rail are always in surface contact, and the guide rail will not be damaged, thereby ensuring the operating accuracy of the slider and extending the service life of the press transmission system and the mold.
